Given that the sites were close to a huge passenger pigeon roost documented by John James Audubon in the nineteenth century and that Cahokians consumed almost every other animal protein source available,the archaeologists conducting the studiesconcluded the passenger pigeon population had once been very limited before increasing dramatically in post-Columbian America. Other archaeologists have criticized those conclusions on the grounds that passenger pigeon bones would not be likely to be preserved. But all the archaeological projects found plenty of bird bones and eventiny bones from fish.阅读-选项passage 1151.The author of the passage mentions “tiny bones from fish” primarily in order toA. explain why traces of passenger pigeon are rare at Cahokian sitesB. support a claim about the wide variety of animal proteins in the Cahokian dietC. provide evidence that confirms a theory about the extinction of the passenger pigeonD. cast doubt on the conclusion reached by the archaeologists who conducted the studies discussed in the passageE. counter an objection to an interpretation of the data obtained from Cahokian sites2.Which of the following, if true, would most call into question the reasoning of “the archaeologists conducting the studies”?A. Audubon was unable to correctly identify twelfth-century Cahokian sitesB. Audubon made his observations before passenger pigeon populations began to decline.C. Passenger pigeons would have been attracted to household food trashD. Archaeologist have found passenger pigeon remains among food waste at eighteenth-century human settlementsE. Passenger pigeons tended not to roost at the same sites for very many generations阅读-正文Passage 168A hoard of coins recently unearthed at an ancient Carthagian site bear an image of a face in profile with what appears to be a large mole on the cheek. Pointing out that an artist would be unlikely to include such a specific detail in a generalized portrayal of a face, some archaeologists have concluded that these coins portray an actual individual rather than an idealized type. However, this conclusion is unwarranted, since _.阅读-选项passage 168Which of the following most logically completes the argument?A. archaeologists cannot determine the actual identity of the individual portrayed just from the likeness that appears on the coinsB. it cannot be established with certainty that Carthagian artists were on the whole less skillful at portraying human face than artists of other culturesC. none of the other designs of Carthagian coins that have been discovered features a face with a mole on itD. in ancient times it was quite common for the money circulated in a city or country to include coins that originated in other jurisdictions.E. the relatively soft metal used for Carthagian coin molds sometimes resulted in the production of series of coins with unintended bumps阅读-正文Passage 29Which of the following most logically completes the argument?A. archaeologists cannot determine the actual identity of the individual portrayed just from the likeness that appears on the coinsB. it cannot be established with certainty that Carthagian artists were on the whole less skillful at portraying human face than artists of other culturesC. none of the other designs of Carthagian coins that have been discovered features a face with a mole on itD. in ancient times it was quite common for the money circulated in a city or country to include coins that originated in other jurisdictions.E. the relatively soft metal used for Carthagian coin molds sometimes resulted in the production of series of coins with unintended bumps阅读-选项passage 291.The author of the passage implies which of the following about the release of water from glacial Lake Agassiz?A. The notion that the release occurred has been challenged by more recent findings.B. The release probably occurred much earlier than scientists have generally assumed.C. The release would not have been sufficient to cause any temperature change in the North Atlantic.D. The timing of the release is such that it probably did not trigger the onset of the Younger Dryas. E. The release was probably unrelated to the global warming trend that was taking place.2.The passage is primarily concerned withA. presenting evidence that undermines an explanationB. explaining the nature of a climatological phenomenonC. questioning the timing of a particular eventD. discussing a new explanation for a phenomenonE. suggesting revisions to a popular theory阅读-正文Passage 129A critical consensus has emerged that Mary McCarthy will be remembered primarily as an essayist rather than as a novelist. But despite her formidable gifts as a polemical and discursive writer, and for all her reputation as an intellectual who sacrificed feeling to intelligence, what powers McCarthys best essays are her fictional rather than strictly intellectual gifts. She makes her points by telling stories or by way of vivid description, arresting images and subtle characterization. And for all her exacting sense of fact, McCarthys greatest contribution was to blur the distinctions between different kinds of prose writing: to show how fiction could be opened up to the thinking mind and how essays could profit from the techniques of fiction.阅读-选项passage 129For the following question, consider each of the choices separately and select all that apply.1.The author of the passage suggests that Mary McCarthys writing is characterized byA. The use in her essays of devices more typical in works of fictionB. A narrowing of the differences between narrative and expository proseC. Careful attention to factual accuracy.2.In the context in which it appears, “discursive” most nearly meansA. prolificB. sophisticC. ramblingD. analyticalE. circuitous阅读-正文Passage 230In the shallow end of Lake Tomwa, there are remains of numerous Jeffery pine trees that grew there during a lengthy drought. Researchers had believed that this drought lasted at least 150 years, but carbon dating reveals that pines were growing in the lake bed for only 120 years, from 1200 until 1320. Since the Jeffrey pines, which cannot survive in water, must have died at the end of the drought, the dating shows that the drought lasted less than 150 years.阅读-选项passage 230The argument given relies on which of the following as an assumption?A. No other species of tree started growing in the bed of Lake Tomwa after 1200.B. No tree remains of any kind are present at the bottom of deeper parts of Lake Tomwa.C. There was at least one tree in the lake bed that was alive for the entire period from 1200 to 1320.D. There has not been a more recent drought that caused a drying up of the shallow end of the lake.E. The shallow end of the lake had been dry for less than 30 years by the time Jeffrey pines started growing in the lake bed.阅读-正文Passage 13Biologists have long debated about whether egg production in birds is biologically highly costly, some theorizing that egg production is energetically or nutritionally demanding. Lack, however, suggested that clutch sizethe number of eggs a bird lays per breeding cycleis far below the potential limit of egg production. He suggested that clutch size had instead evolved in relation to the number of young that the parents could successfully rear. Subsequently, most studies focused on limitations operating during chick rearing, particularly among altricial species (species in which the parents feed their young in the nest). Lack later recognized that in precocial species (species in which young feed themselves), clutch size might be explained by different factorsthe availability of food for egg-laying females, for example.阅读-选项passage 131.The passage suggests that biologists who say egg production in birds is biologically highly costly would agree that clutch size is determined primarily byA. the nutritional and energy demands of egg productionB. the number of young that the parents can rear successfullyC. reproductive limitations operating during chick rearingD. the availability of food for newly hatched chicksE. the differences between altricial and precocial speciesConsider each of the choices separately and select all that apply.2.The passage suggests that Lack would agree with which of the following statements about factors affecting clutch size in birds?A. In altricial species, clutch size is determined primarily by factors operating after eggs are laid.B. In precocial species, clutch size is determined primarily by factors operating after eggs are laid.C. In many bird species, clutch size generally remains well below the potential limit of egg production.阅读-正文Passage 53The manuscripts of the eight extant Latin tragedies identify the plays as the Marci Lucii Annei Senecae Tragoediae. Since nobody of that name is known, modern scholars believe the dramasto be the work of Lucius Annaeus Seneca the Younger, the well-known philosopher, orator and politician. Clearly the tragedies were written during Senecas lifetime: internal references to earlier poets, most notably Ovid, indicate that the dramas cannot have been composed prior to the second decade C.E., and the plays must have been written by 96C.E., when Quintilian quotes Medea, one of the tragedies.It is remarkably, however, that Seneca himself never mentions the plays, since there are certain passages in them that could be used to illustrate points of his philosophy. There are at least two possible explanations. In
